I don't think the atmosphere has changed, other than the extremely minor annoyance I have that the left hand post column is a bit wider when a contributor posts now due to the silver/gold/platinum image. =)
Having said that, I'd love to contribute, but my finances don't have wriggle room at the moment, so I can't. But...I don't feel pressured to contribute. I know I'm still loved and accepted for just who I am. =)
Ahem brother.
